Black flicker and pink buttons.

Hi! I got a problem after installing SP2.

Computer:
1,9Ghz
700MB RAM
Nvidia Geforce2 MX 64mb, updated driver.
Windows XP SP2, fully updated.

Mainly when using IE, the screen frequently goes black for a second or two.
Picture then reappears. No clicking sound. This is most frequent when having
two or more IE windows open, and many images. The black screen usually kickes
in when i scroll down in the browser.

Also, many buttons are turning pink.
No, i do not take drugs.
Especially the "Windows marketplace" button, "back" and the lower left
status bar on IE do this. The latter also tend to turn red for some seconds.
Minimizing and maximizing the window again solves the problem.

I have installed the nevest drivers from NVidia without fixing it.

Any idea what this is?

Regards,
Anders

I think I solved the problem. I installed a USB card today, and did some
clean up at the same time. The processor on the graphics card was loaded with
dirt. At the moment, the problems is gone.
I think all this might have been due to a heat buildup in the processor.

What do you think? Plausible?
